    We do not service Diesel  E-tec or BMW index injectors(piezo)

    At SouthBay Fuel Injectors, we recognize the critical role of fuel injector maintenance in maximizing engine performance and fuel economy, particularly with the addition of ethanol to modern gasoline. We advocate for off-the-car fuel injector cleaning as an essential maintenance practice.

    In contrast to temporary solutions offered by "out-of-the-can" cleaning products, which may introduce contaminants into the fuel injector's sensitive filter, our professional cleaning service guarantees a complete restoration of the injector's functionality.

    Our method employs the latest ASNU Flow Benches, celebrated for their precision and dependability. This established technique allows us to thoroughly clean fuel injectors and return them to their original condition. Our service extends beyond cleaning, including the replacement of all essential components such as o-rings, pintle caps, spacers, and filters.

    Opting for our services grants you access to the advantages of expertly cleaned fuel injectors, all at a cost significantly lower than buying new ones.

    We prioritize quality and take pride in our ability to bring your fuel injectors back to optimal performance.

    To summarize, our services include:

    • Thorough off-the-car fuel injector cleaning
    • Restoration of 100 percent of the injector's function
    • Replacement of all necessary parts, including o-rings, pintle caps, spacers, and filters
    • Utilization of the latest ASNU Flow Bench's for accurate and reliable cleaning
    • Cost-effective solution compared to purchasing new or rebuilt fuel injectors

    At SouthBay Fuel Injectors, we are committed to providing the best fuel injector maintenance services to ensure your engine's performance and fuel efficiency.

    Benchmark test injectors

    At SouthBay Fuel Injectors, we understand the importance of setting a benchmark to accurately compare the before and after results of our fuel injector cleaning service. That's why we have a comprehensive testing process in place.

    When injectors arrive at our shop, we subject them to a thorough test bench evaluation. This evaluation includes testing for leakage at 80 psi to identify any potential issues with the injectors. We also conduct both static and dynamic flow tests to measure their fuel flow rates.

    During the testing process, we meticulously record all the results, including the leakage test and the static and dynamic flow rates. These results will be compiled and included in your service report.

    OHM test injectors for maximum electrical performance

    One of the best ways to check for faulty injectors is to use a multi-tester, sometimes called a multi-meter. Testing continuity by using the OHM setting will tell you if the connection through injector is within normal limits or if it has opened and is no longer useable.

    Remove internal filters, O-rings and pintle caps

    External parts and filters tend to deteriorate with time and extreme operating conditions and stress from everyday use. Never reuse these parts.

    Clean external injector body ultrasonically

    Ultrasonic cleaning is indeed a widely used method that utilizes the power of high-frequency pressure waves to agitate a liquid, creating cavitation bubbles. These bubbles generate intense forces that effectively remove contaminants from various substrates such as metals, plastics, and ceramics.

    The principle behind ultrasonic cleaning involves the penetration of blind holes, cracks, and recesses, ensuring a thorough removal of contaminants that may be tightly adhering or embedded onto solid surfaces. The agitation and collapse of the cavitation bubbles create a scrubbing action that dislodges and disintegrates the contaminants.

    Clean fuel injector internally with ultrasonic technology

    The principle behind ultrasonic cleaning involves the penetration of blind holes, cracks, and recesses, ensuring a thorough removal of contaminants that may be tightly adhering or embedded onto solid surfaces. The agitation and collapse of the cavitation bubbles create a scrubbing action that dislodges and disintegrates the contaminants.

    The equipment used in ultrasonic cleaning typically operates within a frequency range of 20–400 kHz. The specific frequency depends on the application and the type of contaminants being targeted. Additionally, an appropriate cleaning solvent is chosen based on the nature of the contaminants and the material being cleaned.

    Flow test to verify proper atomization and injector flow characteristics

    Ultrasonic cleaning has proven to be highly effective in achieving deep cleaning and removing even stubborn contaminants. Its ability to reach difficult-to-access areas makes it a valuable technique in various industries, including automotive, medical, electronics, and more.

    By utilizing ultrasound and the appropriate cleaning solvent, ultrasonic cleaning provides a thorough and efficient method for removing contamination from solid surfaces, resulting in improved cleanliness and performance.

    Use the best fuel injector calibration fluid

    At SouthBay Fuel Injectors, we prioritize accuracy and precision in our testing procedures. To ensure reliable results, we use only the best calibration fluid in all of our test equipment. This calibration fluid is carefully selected to closely mimic the properties of gasoline without actually using gasoline itself.

    Specific gravity is an important measurement used in our testing process. It refers to the ratio of the density of a substance to the density (mass of the same unit volume) of a reference substance. In our case, the reference substance is gasoline. By comparing the specific gravity of the calibration fluid to that of gasoline, we can accurately assess the performance of the fuel injectors.

    To maintain consistency, all of our tests are conducted using SouthBay's Calibration Fluid at a controlled temperature of 20°C (±1°C), pressure of 3.0 Bar (±0.01 Bar), and a voltage of 13.8VDC (±0.05VDC). The injectors are tested using a saturated driver with an RC cutoff to ensure accurate and reliable results.

    Reassemble Injectors

    At SouthBay Fuel Injectors, we take pride in providing a comprehensive and thorough cleaning process for fuel injectors. As part of this process, we replace all the parts that are removed from the injector prior to the external cleaning.

    When disassembling the injectors, we carefully remove components such as filter baskets, O-rings, spacers, and seals. These parts are then replaced with new OEM (Original Equipment Manufacturer) parts that are specifically fitted to your particular injector model. We prioritize using the highest quality parts available to ensure optimal performance and longevity.

    For older style injectors with a metal body, we go the extra mile to protect against rust and prolong the injector's lifespan. These injectors receive a coat of high-temperature ceramic, which acts as a protective barrier to hold down rust and enhance durability.

    By replacing worn or damaged parts with new OEM components and applying a high-temp ceramic coating to metal-bodied injectors, we ensure that your fuel injectors are restored to their optimal condition. Our goal is to provide you with fuel injectors that perform reliably and effectively, while also extending their overall lifespan.

    At SouthBay Fuel Injectors, we are committed to delivering a comprehensive cleaning process that goes beyond just external cleaning. By replacing necessary parts and providing additional protection for metal-bodied injectors, we strive to provide you with fuel injectors that meet the highest standards of quality and longevity.
